Automated semantic versioning for travis-ci or any other ci

I am using https://github.com/fsaintjacques/semver-tool to auto version my builds:

examples:

for patch level

$ git commit -m "[patch] few changes"

for minor patches

$ git commit -m "[minor] added the foo feature"

for major patches

$ git commit -m "[major] added breaking change"

Very cool. I looked into semantic-release but that was for versioning npm deploys and I'm just interested in bumping the version in package.json and mostly corresponding Github tags. Do you have example of the .travis.yml config to incorporate this script or are you still using this?

@mikesparr: I used in the travis.yml like so:

anguage: python
cache: pip
sudo: required
script:
- echo "yes!"
branches:
  only:
  - next
after_success:
- curl https://gist.githubusercontent.com/lxhunter/9d4310462b6972a3f57b5f914543fd51/raw/semver.sh | bash

Is there any sort of special process you have to do to get this to work? Looks like the tags aren't getting pushed back to github in my repo...

@proegssilb: sorry just saw your comment... how may i be of help?

for all interested: i moved to https://github.com/semantic-release/exec for this
